Each lug has formed therein apair of openings 30 and31 and a pair of wings are 25 and mounted between the lugs, each wingbeing' formed of resilient material, preferably wire,

and having outturned lugs stand 36 which are pivotally mounted in the'openings' 3O orv 7 31of the lugs 25 and26. From theshowing in Fig. 1, it will be seen that theendportions; of the wings are bent-at an angle, as shown at 38, forming cams, between the U-shaped r the Wings.

portion of the wing and the outturnedends 35 and 86. l Due to theengagement of theangular portions 88 off the wings with the inner surfaces of the lugs 25 and 26 the pivoted ends Of the wings will move toward each otheras'the wings are folded and the legs 40 and 41 of the wings will be constricted, as shown in Fig. 5. hen the wings are released they will automatically spring out- W y'or spread to thQPOSlt-lOITShQWIl in Fig. 2. c. l

In order to facilitate the insertion of the toggle bolt through a hole. means is provided for holding the; wings in retracted position. In. the forin'iof the invention illustrated in Figs. 1 to 6 inclusive, this means consists of a latching. device 45 having'an eye 46 at one end loosely pivoted on one of The latch also hasa hook 47 at the other end thereof and a tab 48 extending beyond th'e'hook. p

When the device is to be inserted in a hole,

thelatch'is positioned i as shown in Fig; 1,

and holds the wings in substantially parallel osition." As the device is inserted throu h spread or expanded position by the wall of f 45 thehol'e, the latch will engagethe outer surface of the wall and wi1l"be"'moved along the wings until the end thereof rhavingthe hook 'is' released from engageinent with the wing. The wings will'then 'spri'ngoutwardly but willbe held against movement totheir the openinguntilthe ends of the wing clear the opening. The wings will thenibeautomaticallylspreadjto the position shown in Fig.2 and since the latchin'creases the weight L of the wing attached thereto, 'the device will take the position illustrated'in Fig. 2 and will beheld in this position by the Weight of the latch as the bolt is threaded through'the saddle or nut. V I

In the form of the invention illustrated in Figs? toll inclusive, thereis shown a toggle bolt having a single wing. The wing 50 in this case is channel shaped and is pivotally mounted on a tubular nut51 which is threads ed on the bolt 22.v A spring 52 is disposed within the tubular nut and has one end .53

engaging the nut and the other end'l54 positioned through an opening 55 in the wing 50. The spring tends to swing the wing to 'a posit-ion substantially at right angles to "the bolt. This form oftoggle boltis fully denut 51.

scribed and claimed in copending application Serial No. 38,194, filed June 19,1925. In order to hold the wing 50 in a position substantially parallel to the bolt, as shown in Fig. 7 alatch is pivoted at 61 to one sidej62 or the channelled wing- The other end GS oi-the latch is inserted in an elongated notch6'5 "formed in the otner side or" the channelled wing lWhen the latch is so positioned as shown inFigs. '"(jand 8, the bolt 22 will be retained between the two sidesotthe wing.

The, device is then inserted through the hole in the manner shown in 7 and when the outersurface ofitlie wall is engaged by the end 63 of the latch, the latch will be released from the notch 65 and will permit the'spring 52 to swing the wing. 'After the wing has 'passe d i'hroughthe opening, the weight of the latch willtend to hold the wing from turning as the bolt isthreaded through the In the :form of the invention illustrated in Figsldand 11, the construction is similar to that illustrated in Figs. 7 and 8, but'differstherefroni in that both sides of the wings are'provided with notches extending longitudinally therein from the end thereof. A

latching-pin 71 is inserted in the notches 70, as shown-in Fig. '11, and thectwo ends 7 2 and 7235f the pin extendlaterally trorn'the wing and are adapted to engage the outer surface of the wall as ghe' w'ing is insertedinthe wallopening' 1 InFigs. 12, 13 and 14:, there is shown a toggle bolt comprising a saddle 75 which is threaded on the bolt an has pivotally 5 mounted thereon a. pair'ot' wings 7 6 and 77.

One of the wings has a weight 78 on its outer invention is caoableot modification and that changes in the construction and in the arrangement of the various cooperating parts be made WlllllOUt departing from the spirit or scope of the invention, as expressed in the following claims. 7
